IMPROVEMENT IN DEVICES FOR SECURING AND PROTECTING TAPES.

Specification forming part of Letters Patent No. 192,136, dated June 19,1877; application filed April 25, 1877. 7

To all whom it mag concern:

Be it known that we, WILLIAM H. STAF- FORD and Shannon 8.00011, both ofWoonsocket, in the county of Providence and State of Rhode Island, haveinvented Improvements in a Device for Securing and Protecting Tapes; andwe hereby declare that the following is a full, clear, and exactdescription of the same, reference being bad to the accompanyingdrawings, forming part of this specification.

Figure 1 represents a coil of tape or other similar material, and Fig. 2a wire spring in perspective.

The object of this invention is to firmly secure tape or other narrowfabric to a central spool so that any desired quantity may be unwound orrewound, and the tape be always firmly retained, not only to secure theend, but to allow a roll of tape to be handled and thrown about withoutinjury; and it consists in the use of a curved wire spring, made bybending a piece of wire and securing the ends at the center of thespool, as will be more fully set forth hereinafter.

In the drawings, a is the spool; b, the bent wire spring; and c, thetape or other narrow fabric. The spring 11 is made by bending a wire, asshown in Fig. 2. The two ends enter the hole in the center of the spool,and are bent so as to pass on a curve along the sides of the wound tapeand press on the periphery with the portion uniting the two sidesprings. When the tape is wound or unwound the wire spring b will alwayshold it firmly to the spool. The two springs, forming the two curvedsides, form a guide in winding, and the parts thereof which are securedin the center and united at the periphery form a strong support to thetape on the spool, holding the same firmly, not allowing the center tobe pushed out, and thus the whole spool may be unwound by the ordinaryhandling, or the usual throwing from one person to another, when severalpersons are using tape or other narrow fabric from the same spool.

When a clip is secured by elastic material,

such as rubber, in the center of the spool, narrow tape-and particularlywhen the spool hold the same.

'In Fig. 1 the spring-clip is shown in solid lines on a full, and inbroken lines on anearly empty, spool.

Spools of tape and other narrow fabric must be handled so much, andusually by persons Whose time is truly money, that any advantages gainedin their use become of great importance, not only to the sewing woman,but to the trade.

Heretofore springs have been formed from sheet metal, the same beingsecured to or forming a part of sheet-metal supports, which were pivotedto the axisof the spool. This construction has been found defective inthis, that by securing the two supports together, either by the springitself or by the separate strip of metal to which the spring wasattached, thecapacity of the spool to the amount of material that couldbe wound. between the axis of the spool and the said strip was limited.Our construction entirely obviates this objection by dispensing with.the said strip altogether, and making the entire spring and support ofspring wire, whereby the capacity of the spool may be greatlyincreased,- the only limit to such capacity being the space between theaxis of the spool and the connecting-bar that joins the two curvedsprings 11 b.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- The combination, with the spool 11, of thecurved wire spring b, pivoted directly to the spool, arranged to supportthe sides of the tape-roll and to press upon the periphery,substantially as and for the purpose described.
